Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a method for producing at least one supported endless yarn for the production of large quantities of false-twisted synthetic endless yarn, the assembly of which is driven by an electric motor. Concerning a false-twisted textured aggregate with an axis.

[Conventional technology]

Electric ia! Textured assemblies driven by one machine are known, but in practice only textured assemblies with externally mounted electric motors are found. DE 28 20 816 A1 describes a spinning or twisting machine in which a series of spindles are driven by individual electric motors. A texturing machine is shown in this specification. In this case, the drive motor is mounted on an adapted substrate outside the assembly. The drive of the assembly takes place in this case via a toothed belt drive.

Mounting the drive motor externally involves a series of disadvantages. In addition to the very space-consuming and necessarily protruding design, relatively long drive belts are very disadvantageous, especially with regard to noise generation. Since only one toothed belt is used, in this case additional tightening has to be done by incorporating rollers, so a total of four toothed discs or gears are used, which can be Conversion causes premature wear.

Further technical and economic disadvantages arise from the configuration of the aggregates already described. Whether replacing a bearing, repairing a disc, replacing a disc, replacing a toothed belt, etc., the entire assembly including the electric motor has to be removed from the machine. In this case, several factors are involved not only during disassembly, but also during assembly, such as the cabling of the electric motor, the adjustment of the assembly with all additional equipment. In addition, there is a drawdown time that can lead to production interruptions.

Another publication, Federal Republic of Germany Patent Application No. 26079
No. 20 shows and describes a texturing machine based on the frictional false-twisting principle.

The assembly shown here has three electric chains, each set of discs having an electric motor installed therein.

In addition to the unacceptably high economic outlay, this type of configuration is also unfeasible from a technical point of view. A set of such discs is used at rotational speeds of up to 12,000 revolutions per minute and must rotate without imbalance.

It is obvious to any person skilled in the art that this is not possible in a rotating outer ring (FIG. 3) and can only be done under very expensive and difficult conditions (FIG. 4). Furthermore, the rotation of the disc, which is essential for good yarn quality, cannot be achieved with the required quality. In this case, it is additionally added that, for example, in the event of wear of only one disk, the complete set of disks including the rotor can no longer be used. The confined configuration (see FIG. 3) also presents great difficulties to those skilled in the art during assembly and disassembly.

Another drawback consists in the mutual synchronization of the three motors. This is because the three sets of discs must not have a difference in rotational speed, otherwise this would result in difficulty in starting the yarn or - poor yarn quality.

[Problem to be solved by the invention]

An advantage of the present invention is to avoid the above-mentioned drawbacks and provide an electric motor-driven textured aggregate that is technically and economically acceptable and can be easily assembled and operated. .

[Means to solve the problem]

This 'i3 problem is such that the shaft inside the assembly is configured to support the rotor of the electric motor, and the stator is housed in a motor block fixedly attached to the machine and separated from the rotor shaft. The solution is that the &Im4 elements, such as gear toothed belts and/or round or flat belts, lead to separate shafts and synchronous drives.

Further advantageous developments can be seen from the embodiments of the patent claims 2 to 4.

The invention starts from the false-twisted textured assemblies mentioned at the outset, in which case there are triaxial friction disc assemblies, electromagnetic false-twisting assemblies or l-axis disc assemblies. It doesn't matter whether or not.

One of the aforementioned shafts is configured such that the motor rotor is mounted on this shaft. To this end, for example, when refitting an existing assembly, it is possible to use the shaft of a bearing that was previously equipped with a drive flywheel for the ripping drive, in which case only the flywheel needs to be removed. .

A stator is fixedly installed within the motor block or housing. The fixation of the rotor in the stator takes place via double bearings of the assembly, which carries the friction discs and the suitably constructed motor block, so that no other fixation is necessary. . The motor block is fixedly attached to the spindle of the machine and does not have to be removed from the machine in the event of repairs. Another advantage is that, for example, thread monitoring devices that require very precise adjustment, or similar devices that were previously integrated into the assembly and were attached to each new assembly and during repairs etc., can be It consists in being integrated into the motor block remaining in the motor block and thereby not being exposed to any risk of damage. Furthermore, the cabling or cabling for the data detection device during removal/during the assembly is no longer affected. Production interruptions are largely prevented by the immediate use of the assemblies introduced in the 84111 aircraft block only.

Readjustment is no longer necessary.

In addition to all these advantages, further advantages are added during new and retrofitting of machines. Conventional tangential belt drives and all belt clamping and turning elements and support arrangements for the assembly are dispensed with. Individual adjustment devices of the clusters and other elements for the drive belt are also not required.

Accompanying this are significant energy savings and a distinct reduction in noise production which negates the economic advantage over all previously available devices.
